Curb mounted vs. deck mounted skylights, we’ll help you determine which type of skylight is best for your home in this in depth comparison.

Skylights, an essential feature in modern home design, offer more than just a visual appeal. They illuminate interiors with natural light, enhancing the ambiance of a living space. In this realm, two predominant types stand out: curb-mounted and deck-mounted skylights. Each type brings a unique set of characteristics and installation methods, fitting different needs and roof types. Curb-mounted skylights, known for their ‘shoe box lid’ design, require a pre-built curb for installation. In contrast, deck-mounted skylights are directly attached to the roof deck, offering a lower profile and sleek integration.

This article delves into the specifics of these two popular types. We will explore their design features, installation requirements, and how they sit on your roof. Whether you’re considering a new installation or planning to replace an existent one, understanding these differences is crucial. It ensures that you choose a skylight that not only brightens your home but also aligns seamlessly with your roof’s architecture.

In the upcoming sections, we’ll break down the intricacies of curb-mounted and deck-mounted skylights. From the process of building a curb to the nuances of attaching a skylight to the roof deck, we aim to guide you through each step. By the end of this article, you’ll be equipped with the knowledge to make an informed decision about the type of skylight that best suits your home.

Curb-Mounted Skylights

Curb-mounted skylights, a popular choice for many homeowners, are renowned for their versatility and robust design. This type of skylight sits on top of a curb, much like a lid on a shoe box. The curb, essentially a raised frame, is built on the roof deck, creating a platform for the skylight.

Building the Curb

The construction of the curb is a critical step in the installation of a curb-mounted skylight. It involves using lumber to build a frame that will elevate the skylight above the plane of the roof. This elevation is not just for aesthetic purposes; it’s a crucial factor for effective water drainage and weatherproofing. The curb must be engineered to match the dimensions of the skylight, ensuring a snug fit.

Flashing kits, typically provided by skylight manufacturers like VELUX, play a vital role here. They include custom-sized underlayments and other materials to create a watertight seal between the skylight and the curb. Proper installation is key to prevent leaks and ensure durability.
